When is dna content halved

Reason : In meiosis, there is no DNA rep The DNA content of a diploid cell in the G phase of the cell cycle is measured. If this DNA content Chromosome number is halved in meiosis during. Differentiate between meiosis-I and meiosis -II. In Meiosis-I and meiosis-II, which is similar to mitosis? Stage connecting meiosis I and meiosis II is. When a cell is produced through fertilization or cell division, there is usually a lag before it undergoes DNA synthesis replication.

This lag period is called Gap 1 G 1 phase , and ends with the onset of the DNA synthesis S phase , during which each chromosome is replicated. Following replication, there may be another lag, called Gap 2 G 2 phase , before mitosis and cytokinesis M phase. Cells undergoing meiosis do not usually have a G 2 phase. Interphase is as term used to include those phases of the cell cycle excluding mitosis and meiosis. Many variants of this generalized cell cycle also exist. Some cells never leave G 1 phase, and are said to enter a permanent, non-dividing stage called G 0 phase.

Many variants of this generalized cell cycle also exist. Some cells never leave G 1 phase, and are said to enter a permanent, non-dividing stage called G 0. On the other hand, some cells undergo many rounds of DNA synthesis S without any mitosis or cell division, leading to endoreduplication.
